- 'To eliminate identifying proteins on the organs for transplants.'

Explanation:

A research is always conducted with a pre-defined purpose and goal that is required to be accomplished by the conclusion of the research.  

As per the given description, the most likely purpose of this research of 'genetically engineering the organs' conducted by the scientists is 'to remove the distinguishing proteins on the organs for transplants'. This research would allow the transplant of organs more convenient(after being able to identify and remove the histo-compatibility complex proteins).
